Cleaning dust on photos: or “In Gimp We Trust!”

Filed under
GIMP

I bought a real camera for me: a Nikon D40 – which is, according to many, many people, is the best DSLR out there. I could not ever EVER got close to those pictures with all my previous cameras. I found out that it came with some dust on its sensor. So the next step was to start thinking like a computer geek.

So another option was to clean the dust in gimp. Manually… and it is needless to say that this approach is.. well.. boring, time-consuming and pretty much futile.

However, when all the hope was, apparently, lost, the Great Google Gods sent me a wonderful link to the Resynthesizer plugin – which is AMAZINGLY EFFICIENT in solving the dust issues.

diff -u: What's New in Kernel Development

Alexander Holler wanted to make it much harder for anyone to recover deleted data. He didn't necessarily want to outwit the limitless resources of our governmental overlords, but he wanted to make data recovery harder for the average hostile attacker. The problem as he saw it was that filesystems often would not actually bother to delete data, so much as they would just decouple the data from the file and make that part of the disk available for use by other files. But the data would still be there, at least for a while, for anyone to recouple into a file again. Alexander posted some patches to implement a new system call that first would overwrite all the data associated with a given file before making that disk space available for use by other files. Since the filesystem knew which blocks on the disk were associated with which files, he reasoned, zeroing out all relevant data would be a trivial operation. Read more

8 Linux Security Improvements In 8 Years

At a time when faith in open source code has been rocked by an outbreak of attacks based on the Shellshock and Heartbleed vulnerabilities, it's time to revisit what we know about Linux security. Linux is so widely used in enterprise IT, and deep inside Internet apps and operations, that any surprises related to Linux security would have painful ramifications. In 2007, Andrew Morton, a no-nonsense colleague of Linus Torvalds known as the "colonel of the kernel," called for developers to spend time removing defects and vulnerabilities. "I would like to see people spend more time fixing bugs and less time on new features. That's my personal opinion," he said in an interview at the time. Read more

Linux from Square One

Despite the fact I have a different view of which distros are best for kids — Qimo (pronounced “kim-o,” as in the last part of eskimo, not “chemo”) tops the list, as it should, but the French distro Doudou (add your own joke here) is unfortunately left out — the link there is informative. So for those who are just getting their proverbial feet wet in Linux, this is a godsend. Read more
